First to find the area the formula is A=pi(r^2)
so plug in the numbers                   A= (3.14)(4.5)(4.5)= 63.62 is the total area

150*63.62=9543         9543/360=26.5


So the answer is 26.5 cm ^2

\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta \pi r^2}{360}~~
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad degrees\\
------\\
r=4.5\\
\theta= 150
\end{cases}\implies A=\cfrac{(150)(\pi )(4.5^2)}{360}

Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring:
andre [41]
The part of the quadratic formula that dictates whether the function is factorable or not is B. b^2 - 4ac. This determines the number of real, imaginary, negative and positive roots. 
In the equation <span>2x^2 + 7x + 3, 
we use the quadratic formula 
x = -b +- sqrt (b2 -4ac) /2a = -7 +- </span><span>sqrt (49 -24) /4
the answers are x1 =-0.5 and x2 = -3.</span>
